Danny Ainge has said publicly that the Celtics aren't rebuilding, and that he's not trading Rajon Rondo. Be that as it may, the Detroit Pistons have let it be known how to reach them if Ainge changes his mind.

In the aftermath of the Celtics' decision to ship Kevin Garnett and Paul Pierce to Brooklyn last week, the calls have been coming in -- chiefly, regarding Rondo. The logical assumption was that if the Celtics didn't want to pay Doc Rivers $7 million to coach a rebuilding team, and if Garnett and Pierce didn't fit into those plans, either, then Rondo would be the next to go.

Based on that possibility, the Pistons were among the first teams to reach out to the Celtics and express interest in acquiring Rondo, the All-Star point guard who is coming off an ACL injury, league sources told CBSSports.com. Having already made lucrative pitches to free agents Josh Smith and Andre Iguodala, Pistons president Joe Dumars also has registered interest in Raptors forward Rudy Gay, one source said.
